Project Blue Book Mantell case file (92 pages)

USAF / NARA via The Black Vault · 93 pages · text by GLM-OCR

This 92-page Project Blue Book file, released through The Black Vault, covers the 7 January 1948 sighting at Godman Field, Fort Knox, Kentucky. It holds control tower witness reports, a record of the P-51 pursuit led by Captain Thomas Mantell, AMC requests for theodolite readings and weather data, and astronomical tables for Venus and the Moon. One analysis concludes the object was not Venus and calls the sighting unexplained. The file also includes a 1964 letter to the Simpson County coroner about Mantell's death.

Read from the scan by GLM-OCR; expect the odd misread word.

Info taken from reports of radio conversation between Control at Godman and Mg 869 essentially as follows:

Col Hix's account. NG 869: "Object traveling at 180 MPH - half my speed"

T/Sgt Quinton A. Blackwell:

NG 869: At 1445. "Object traveling at 180 MPH Directly ahead of & above me now and moving at about 1/2 my speed."

Later: "I'm trying to close in for better look"

At 15,000 ft: "Object directly ahead of and above me now and moving about 1/2 my speed. It appears metallic of tremendous size. I'm trying to close in for better look"

No other word heard by Blackwell from NG 869.

No further contact heard by Capt Carter - *Apparently last word ever received from NG 869.
